Attitude

Attitude, a photo by pdw's atelier on Flickr.

I understand confidence.
I understand arrogance.
(They're not the same thing.)

What I don't understand is arrogant confidence.
The two become muddled into one and it's difficult to tell where one ends and the other begins.
The arrogance tends to overshadow the confidence and by doing so, all respect is also left behind.
(Some things should never be blended together.)

When combined together, what you're left with is an unbecoming attitude.
